EASTON — Joe Rogier was finishing his shift at the Mobil Oil Station at Five Corners when a man wearing a ski mask and carrying a gun entered the store.

“This is a robbery. Empty the drawers. This isn't a joke,” the man told Rogier, 28.

In just 45 seconds on Jan. 28, Rogier was robbed.

“He was very quiet, very nonchalant,” Rogier recalled.

Rogier noticed something else as he was facing down the man with the gun.

“He had an extra gun clip,” he said.

The armed robbery was one of two within just 30 minutes. The second one was in neighboring Stoughton.

Police believe armed robberies locally are on the rise.

“I think there are more armed robberies in the past year,” said Easton Police Chief Allen Krajcik. “It's unusual.”

In addition to the Mobil station robbery, he mentioned the hold-up by two armed suspects at the Burger King in Easton last summer.

“There are more weapons being shown,” he said.

The sudden, life-threatening event of armed robbery can affect its victims differently, but it affects nearly all of them, said Dr. Barbara Niles, a clinical psychologist at the VA Boston Healthcare System in Jamaica Plain.

“For most people, after having a gun pointed at them, they would have a hard time thinking about it and they might dream about it,” Niles said.

The first few days after a violent episode can trigger worry, anxiety, restlessness and sleeplessness, she said.

“This is very normal initially and you want to talk about it, you don't want to do the stoic thing and pretend it never happened,” Niles said.

She said if more than a month goes by and someone still can't get the images of a violent episode, like armed robbery, out of their mind, and if it is affecting their work, their sleep and other aspects of their life, they might want to talk with a professional.

Sharing and talking about an incident like an armed robbery can help someone process the incident in their mind, because often it is foreign to someone's way of thinking, she said.

“You think your job is safe and in an instant your entire world view can change,” Niles said.

That's what happened to Khan Mudasser when he was robbed at gunpoint 30 minutes after Rogier's robbery.

“He (the gunman) just walked in the front door, he had a mask on and a gun pointed at me,” Mudasser said. “The guy had the gun pointed at both of us behind the counter and said, 'Give me the money. Do you think I'm joking?' So I handed him the register.”

Stoughton police officers who later reviewed the security video told Mudasser that it was a big weapon pointed at him.

Mudasser was calm and able to give police such an accurate description of the suspect's getaway vehicle that a suspect was arrested two days later.

“I'm relieved he's off the streets and can't continue to do what he was doing before,” Mudasser said, adding that he was not nervous about returning to work.

Robbery suspect Serge Andre, 25, of 14 Hillis Road, Hyde Park, was arrested on Jan. 30 by Sharon police and arraigned in Stoughton District Court on a handful of motor vehicle charges.

Those charges included operating on a suspended license, driving an unregistered motor vehicle and a marked lanes violation.

The suspect confessed to both armed robberies, said Easton Police Chief Allen Krajcik.

Andre, who is being held at the Norfolk County Jail, will also be charged by Stoughton police with armed robbery while masked, armed assault to rob, and assault with a dangerous weapon. Easton police will charge him with armed robbery while masked.

Ironically just two days before the armed robbery, Joe Rogier's territory manager stopped by to give him armed robbery training.
